Hereinafter, the embodiment of the ecology detection apparatus according to the present invention will be described in detail together with the embodiment of the ecology detection method.
The ecology detection apparatus according to the present invention includes a reflective film 1 that is attached to the detected object X by any one of application, spraying, and pasting methods, a Doppler sensor 2 that detects a body motion reflection signal in the reflective film 1, and Information station 3 holding clinical parameters indicating the findings derived from body motion reflection signals detected by the Doppler sensor 2 and the degree thereof, and the various ecology of the detected body X and the various manifestations of abnormalities in the various ecology The biological table 4 including the combination of the above and the clinical parameters of the above-mentioned findings, and the biological and physical parameters of the subject X are determined by collating the findings and clinical parameters of the information station 3 with the findings and clinical parameters of the biological table 4 The diagnostic means 5 is provided.

  In the example shown in FIG. 1, the Doppler sensor 2 installed on the detection object X outputs a Doppler wave at a constant cycle for 24 hours a day, and the body movement accompanying the movement of the moving body at a level corresponding to the reflectance. While detecting the reflection signal, the body motion reflection signal reflected by the reflection film 1 attached to the detection object X is remarkably detected as a relatively strong signal having a certain output or more.

  The ecology table 4 lists the ecology to be detected by the detected object X, tabulates combinations of characteristic findings of each ecology, and determines that each of the combined findings is a corresponding ecology. A cumulative threshold of sufficient clinical parameters is set.

  The diagnostic means 5 guides the body motion reflection signal as a component of heartbeat, respiration or motion (hereinafter referred to as body motion data) through real-time spectrum analysis by Fourier transform in the calculation unit 6, and those components. The component is further diagnosed as to the presence or absence of findings relating to heartbeat, breathing or movement, or relative changes in body motion data not belonging to any of them, and if there is a finding, the clinical parameter '1' is set. Output (see FIG. 2).

  The findings of the heartbeat, respiration, and motion are found when a spectrum corresponding to a possible cycle of heartbeat, respiration, and motion of the detection subject X is taken out and the cycle is out of the normal range.

  The diagnostic means 5 stores the body movement data, findings, and clinical parameters generated thereby, linked to the time information in the information station 3 in real time via a wired or wireless communication network (clinical). The parameters are cumulatively added for each finding.) When the clinical parameters are output, the cumulative values of the clinical parameters already stored in the information station 3 and the clinical parameters in the ecology table 4 are displayed. If the combination of findings exceeding the threshold matches the combination of characteristic features (ecological elements) listed in the ecology table 4, the detected object A determination that X indicates an ecology that matches the combination is output.

  The diagnostic means 5 further compares the clinical parameters of the findings stored in the information station 3 with the instruction criteria defined in the instruction table (for example, see FIG. 1) 7, and is determined for each instruction criterion. Encourage appropriate output, such as outputting an alarm based on the degree of tightness.

  In the following, some diagnostic examples will be described in the case where the diagnostic means 5 includes the ecology table 4 shown in FIG. 3A and the instruction table 7 shown in FIG. .

For example, even if the signal level reflected by the reflective film 1 is not reached, the relative change in the body motion reflection signal (body motion data, the same applies hereinafter) of the noise level and the detection level in the specification of the adopted Doppler sensor 2 is observed. , It can be recognized that the ecology of defecation or urination has become apparent as the detection of moisture has become relatively prominent.
Then, the number of clinical parameters related to defecation or urination is estimated as the detected water content, and an output for prompting measures such as emergency, response, standby, and preparation is performed based on the instruction table 7 shown in FIG.

For example, even if the signal level reflected by the reflective film 1 is not reached, the relative change in the body motion reflection signal of the noise level of the Doppler sensor 2 is detected as a finding, and 4 or more clinical parameters are accumulated regarding the findings relating to the heartbeat. In such a case, it is suspected that myocardial infarction is suspected because water has been detected by sweating and the findings regarding the heartbeat have become remarkable.
In this case, according to the instruction table 7 shown in FIG. 4, an output prompting an emergency measure is immediately performed.

  The above example shows a basic embodiment of the ecology detection device according to the present invention, and further detects the overall odor data in the room where the detected object X is placed as shown in FIG. The odor sensor 8 and the information station 3 that holds various parameters derived from the overall odor data detected by the odor sensor 8 and clinical parameters indicating the degree thereof are combined, and the ecological table 4 includes the comprehensive odor data as the various findings. It can also be set as the structure which adds the finding regarding the presence or absence of the odor derived from odor change, or an odor density | concentration (for example, refer FIG.3 (B)).

The presence or absence of the odor mainly indicates the physical condition of the detected object X and the environment where the detected object X is placed, the change in the odor indicates those changes, and the concentration of the odor indicates the degree thereof.
FIG. 3 (B) shows the clinical parameters sufficient to determine that each of the ecology added to the ecology table 4 in this example, the combination of characteristic findings of the ecology, and the combined findings is in the corresponding ecology. It is an example of a cumulative threshold.

  By adding characteristic findings of ecology added by the comprehensive odor data to the ecology table 4, the accuracy in discriminating defecation and urination increases, and it is possible to determine ecology that could not be captured by the Doppler sensor 2 alone It becomes.

  In the biological detection apparatus according to the present invention, when the findings and clinical parameters of the information station 3 are compared with the findings and clinical parameters of the biological table 4, the detected object X is placed on the clinical parameters of the information station 3. In addition, the diagnosis unit 5 may be provided with correction means 9 for adding correction parameters corresponding to individual stress factors.

  The correction parameters corresponding to individual stress factors may correspond to light stress that does not reach the minimum unit of the clinical parameter '1', and may correspond to heavy stress exceeding '1'. In light of the fact that even a light stress may correspond to one or more units of clinical parameters by accumulating multiple times, it may correspond to “emergency” of the instruction table 7 by one detection. There is a need to correct the determination and instructions of means 5.

FIG. 5 is an example of the correction table 10 showing the correction parameters added to the ecology table 4 and the stress factors causing them in this example.
In the correction table 10 of FIG. 5A, correction parameters to be added to the clinical parameters are set for each individual stress factor.
When a clinical parameter is generated as described above, the diagnostic means 5 adds a correction parameter corresponding to a stress factor existing at the time of occurrence of the clinical parameter to the accumulated value of the clinical parameter as a generation factor of the clinical parameter. , Prompting an appropriate output according to the instruction table 7 of FIG.

  For example, even if the signal level reflected by the reflecting film 1 does not reach the signal level, the relative change in the body motion reflection signal of the noise level of the Doppler sensor 2 is detected as a finding, and the clinical parameter is already “1” regarding the respiration finding. In addition, when the clinical parameter of “1” is added and the weather condition due to the typhoon can be sensed at this time, the correction parameter “1” is further added to thereby increase the respiration parameter. The clinical parameter is '3' for the findings. The diagnosis means 5 determines that there is an apnea of 2 minutes or more if moisture is detected by sweating and the findings regarding respiration become prominent, and selects and outputs “correspondence” as an instruction in the instruction table 7.

If the stress factor as shown in FIG. 5B is further added to the above example, for example, if separation and illness are added, the correction parameter becomes 0.6 + 0.5 = 1.1.
In this example, the diagnostic means 5 rounds up the decimal part and adds “2” to the clinical parameter to calculate “5” as the clinical parameter.
In this case, according to the instruction table 7 shown in FIG. 4, an output prompting the “urgent” measure is immediately performed.

The reflective film 1 may correspond to any technique of pasting, applying or spraying on the detection object X. According to the above attachment mode, the operation of attaching the reflective film 1 becomes extremely easy, and the body of the detection object X is not restrained and contributes to reducing the burden.
When applying sticking, spraying type is used (see Fig. 6 (C)), and when applying, ointment or wax-like type (see Fig. 6 (B)) with reduced drying is used. In this case, a spray paste type (see FIG. 6A) in which an aerosol material is enclosed is used.
The Doppler sensor 2 can amplify the reception of the reflected signal by adhering the liquid, but may mix or use metal powder such as aluminum or metal film which is less likely to cause metal allergy.

The reflective film 1 may be directly attached to the skin of the body X to be detected, or may be attached to a device such as a bandage or a cast, or clothes such as pajamas. It is desirable to adhere.
By attaching at least two or more places on the head, neck, chest, lumbar, sacrum, upper limb, or lower limb as the attachment location of the reflection film 1, it is possible to accurately determine the site where the reflection film 1 is attached. The grasping and relative distance, its change and moving speed can be detected without misrecognition, and the body motion obtained from those body motion reflection signals is due to which part of the body to be detected X is due to which organ. It can be estimated accurately.

FIG. 7 shows an embodiment in which the estrus or birth sign of livestock is considered as ecology.
In this example, estrus, childbirth, etc. are set as the ecology to be detected in the ecology table 4, and the combination of characteristic findings of these ecology and the combined findings (whether heartbeat, breathing or action, presence or absence of odor, odor For each of (change or odor concentration), a cumulative threshold of clinical parameters sufficient to determine that the corresponding ecology is relevant, or a combination of findings relating to relative changes in body motion data that do not belong to any of them is set.
